The following CVEs are assigned: CVE-2026-2047.
AI Analysis
Technical Summary
CVE-2026-2047 is a heap-based buffer overflow vulnerability in GIMP's ICNS file parser. The flaw is due to insufficient validation of the length of user-supplied data before copying it into a heap buffer, which can lead to arbitrary code execution in the context of the current process. Exploitation requires user interaction, such as opening a crafted ICNS file or visiting a malicious page. The vulnerability has a CVSS score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). GIMP has issued an official update to fix this vulnerability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the user running GIMP. This can lead to full compromise of the affected system's user context, including confidentiality, integrity, and availability impacts. User interaction is required for exploitation.
Mitigation Recommendations
An official fix has been released by GIMP to address this vulnerability. Users and administrators should apply the update provided by GIMP to remediate this issue. No additional mitigation steps are required beyond applying the official patch.
